Default Barrel Aging and air locks

If using a barrel for secondary aging, it an airlock necessary versus filling to brim and then adding a rubber stopper. Obviously I would need to be certain that the beer had reached terminal gravity.

This is for a first use (non-sour) beer. I am thinking the answer for a sour barrel would be Yes - use an air lock.

thanks

I have a new barrel, and am wondering the same thing. I would assume that an airlock wouldn't hurt anything.

I use an airlock with a barrel. At least in the beginning, there is some dissolved CO2 that gets released in the transfer. Probably after a few days you could replace it, but I'd rather monitor an airlock and come home to a barrel that blew the stopper.

I was thinking along these lines as well. Allow a few days to make sure all is calm. The stand that comes with those Balcones 5 gallon barrels allow them to be stacked but only without an airlock on top

Thanks

How many do you have or how little space do you have that you have to worry about stacking them??

My RIS hit its FG over a week and a half ago. Still put an airlock on the barrel just to make sure it doesn't pop a stopper off when I'm not home.

After racking my first beer into my bourbon barrel all was fine and calm. But when I moved it 30 feet to its resting place the CO2 in suspension was released and foaming occurred (duh). So an airlock was definitely needed.

Took about a day to settle back down.

If you fill it to the brim and put a rubber stopper in it, you would also risk temperature change (increase in temperature causing expansion of the liquid) pushing the plug out.
